[0025] like Figure 1-Figure 6 As shown, the lotus root picking device includes a hull 1 and a storage bin 2, the hull 1 and the storage bin 2 are detachably connected, the hull 1 is provided with a dredging device 3, a grabbing device 4 and a conveying device 5, the dredging device 3 includes a plurality of high-pressure water gun groups 6 and a water pump 7, the water pump 7 is provided with a sand filtering device 8 and a backwashing device 9, the sand filtering device 8 is used to filter mud and sand, the backwashing device 9 is used to clean the sand filtering device 8, the grabbing device 4 is used to pick lotus roots, and the conveying device 5 is used to move the lotus roots from the grabbing device 4 to the storage bin 2.

[0026] To further elaborate, the sand filtering device 8 includes a shell 10 and at least one filter screen 11. The shell 10 is configured to be conical. The shell 10 is provided with a water inlet 12 and a water outlet 13. The filter screens 11 are all arranged at the water outlet 13. The water outlet 13 is detachably connected to the water pump 7. This configuration is used to filter the sediment in the shell 10 and is configured to be conical, which can ensure that the sediment sinks to the bottom under the action of gravity. In this embodiment, two filter screens 11 are provided, namely a stainless steel mesh and a nylon filter cloth. The stainless steel mesh has an aperture of 2 mm and is used to intercept large particles of sediment. The nylon filter cloth is used to block sediment with particles larger than 0.5 mm. A double-layer filter screen 11 is used for filtration to ensure the filtering effect.

[0027] In further detail, a spiral channel 14 is provided at the water inlet 12, and a sand outlet 40 is also provided at the bottom of the shell 10. This arrangement is used to generate a vortex when water flows in, and use centrifugal force to throw the mud and sand onto the inner cavity wall of the shell 10, and leave the shell 10 through the sand outlet 40 at the bottom.

[0028] To further elaborate, the backwashing device includes a solenoid valve 15 and a diversion channel 16. The solenoid valve 15 is arranged at the water outlet end of the water pump 7. One end of the diversion channel 16 is connected to the water outlet end of the water pump 7, and the other end of the diversion channel 16 is connected to the side of the filter 11 away from the shell 10. When the filter 11 needs to be flushed, the solenoid valve 15 is closed, so that the water flows back to the filter 11 from the diversion channel 16, and at the same time impacts the filter 11, and the mud and sand on the filter 11 are reversely flushed into the interior of the shell 10 and leave from the sand outlet 40. After completion, the solenoid valve 15 is reopened.

[0029] To further elaborate, the high-pressure water gun group 6 includes a plurality of high-pressure nozzles 17, a plurality of mounting blocks 18 and two first rotating shafts 19. The mounting block 18 is provided with a through hole 20 for the rotating shaft to pass through. The high-pressure nozzle 17 is arranged on the first rotating shaft 19. The first rotating shaft 19 is used to rotate and drive the high-pressure nozzle 17 to rotate. The high-pressure nozzle 17 is divided into two groups, which are respectively used to remove mud and sand on both sides of the lotus root. The angle of the high-pressure nozzle 17 is controlled by the first rotating shaft 19. The first rotating shaft 19 can be controlled by a motor or manually. At the same time, gear meshing can be used between the two first rotating shafts 19 to achieve simultaneous control of two groups of high-pressure nozzles 17.

The first arc-shaped clip 23 is arranged on the first telescopic rod 21, and the second arc-shaped clip 24 is arranged on the second telescopic rod 22. Multiple first arc-shaped clips 23 and multiple second arc-shaped clips 24 are connected by a second rotating shaft. The surfaces of the first arc-shaped clip 23 and the second arc-shaped clip 24 are provided with a rubber layer to reduce the pressure on the lotus root. The first arc-shaped clip 23 and the second arc-shaped clip 24 are separately regulated, and a motor and a torque sensor can be provided. When the first arc-shaped clip 23 or the second arc-shaped clip 24 touches the lotus root, the torque will increase. At this time, the corresponding arc-shaped clip is stopped until the first arc-shaped clip 23 and the second arc-shaped clip 24 both contact the lotus root. At this time, the first telescopic rod 21 and the second telescopic rod 22 contract to pull the lotus root to make it float to the water surface.

[0031] In further detail, the conveying device 5 includes a driving device 25 and a conveyor belt 26. The conveying device 5 is used to drive the conveyor belt 26 to work. The conveyor belt 26 is used to convey the lotus roots to the storage bin 2. A gathering frame 27 is also provided at the bottom of the hull 1. The gathering frame 27 includes a support rod 28 and a gathering platform 29. The gathering platform 29 is arranged below the conveyor belt 26. The gathering frame 27 is provided to prevent the lotus roots from sliding out of the collection area at the bottom of the hull 1 after floating to the surface. The lotus roots are gathered and conveyed to the storage bin 2 through the conveyor belt 26.

[0032] In further detail, the driving device 25 includes a driving motor 30 and a mounting platform 31 for mounting the driving motor 30 . The mounting platform 31 is disposed on one side of the hull 1 . The driving motor 30 is connected to a driving rod of the conveyor belt 26 .
